Osvaldo Rea-Herrera (“Rea”) appeals the 46-month sentence imposed following entry of his guilty plea to a charge of being found illegally in the United States after he had been removed subsequent to his conviction for an aggravated felony. Rea’s sole issue on appeal is a challenge to the validity of Almendarez-Torres v. United States, 523 U.S. 224, 118 S.Ct. 1219, 140 L.Ed.2d 350 (1998), and the use of his prior conviction to increase his sentence. Rea asserts for the first time on appeal that the “felony” and “aggravated felony” provisions of 8 U.S.C. § 1326(b) are unconstitutional because they are treated as sentencing factors rather than as elements of the offense. Rea concedes that his arguments are foreclosed by circuit precedent and admits that he raises the arguments merely to preserve them for Supreme Court review.

As Rea concedes, his arguments are foreclosed. See United States v. Izaguirre-Flores, 405 F.3d 270, 277-78 (5th Cir.), cert. denied, — U.S.-, 126 S.Ct. 253, — L.Ed.2d - (2005); United States v. Mancia-Perez, 331 F.3d 464, 470 (5th Cir. 2003). The Supreme Court in Apprendi v. New Jersey, 530 U.S. 466, 490, 120 S.Ct. 2348,147 L.Ed.2d 435 (2000), did not overrule Almendarez-Torres, and we must follow Almendarez-Torres “unless and until the Supreme Court itself determines to overrule it.” Mancia-Perez, 331 F.3d at 470 (internal quotation marks and citation omitted).

AFFIRMED.
